I grew up when cameras weren't a thing. We didn't have cell phones, internet, or trail cams. I've had the experience of hunting and scouting sign, terrain, and sheer gut feeling. And now that I'm running dozens of cameras, I still hunt that way.
Cameras aren't a crutch. They don't substitute anything. They're a tool that if used correctly can enhance/aid the hunt by confirming scouting. Take inventory over salt in the summer or watch a scrape in fall, that kind of stuff. But they can be a double edge sword, too. If you leave a bunch of scent or check too often or even lack an understanding of how & where to put them, they can ruin a spot. They can spook deer and you checking them can spook deer. They aren't the given miracle advertising paints them to be.
That said, I rely on them. Maybe not in the way you'd think, though. I've never been able to pattern a deer with a camera. All I can learn is which deer are making and using sign I scouted. And I know when deer begin showing in daylight, in general, during late pre-rut. In that regard the cameras save me lots of wasted time hunting a deer that when I finally see, is not one I want to take. It also saves me from blowing an area out by hunting it while deer are still largely nocturnal. But above all, I enjoy watching bucks grow up through the years and then pick one or two to hunt because I know they are the dominant, most mature deer in the area. Cams are invaluable in many aspects. Just don't let them cripple you.
